Every World Cup writes its own underdog story. In 2002, South Korea reached the semi-finals. In 2018, Croatia stunned everyone by reaching the final. In 2022, Morocco rewrote history as Africa's first semi-finalist, defeating Belgium and Portugal along the way.
Now, with the expanded format of the 2026 FIFA World Cup, the chances of a surprise run are higher than ever. More teams, more matches, and a larger knockout field mean underdogs have more room to dream, and deliver.
Spain (5.55), France (6.00), England (7.10), Brazil (9.10) and Argentina (9.05) dominate the Duelbits Sportsbook outright market. But five teams sitting at significantly longer odds carry genuine analytical cases for a deep run, and potentially one of the most improbable trophies in football history.
Here are the five best World Cup 2026 dark horse bets, with Duelbits prices and the statistical case for each.
All odds from Duelbits Sportsbook, correct at time of writing and subject to change.
The new 48-team World Cup structure is a game-changer for underdogs. With the top two plus some of the best third-placed teams advancing, there's more room for a slip-up, and for surprise packages to squeeze through. Weaker groups mean outsiders can build confidence, and an extra knockout round gives in-form teams even more opportunity to ride momentum deep into the tournament. For any side that can avoid early disaster, the road to the last 16 or even last eight is wide open.
The additional Round of 32 (new in 2026) means a dark horse team that wins its group or qualifies as a strong second can ease into the tournament against a third-placed team before facing a heavier opponent. That transition game is precisely where confident, well-organised outsiders have historically caused the most damage.
Group I: France (Group Favourite), Senegal, Norway, Iraq
To qualify from Group I: Norway - Yes at 1.20, No at 4.40
Norway is another nation that hasn't competed at a finals since 1998, but big things are expected of the Scandinavians this year. That has a lot to do with the strength of its squad, but mostly because of the presence of Erling Haaland.
Few teams outside the established elite can boast a superstar quite like Erling Haaland. Norway's talisman is supported by Martin Ødegaard, a midfield metronome with Premier League class, and a supporting cast that has matured as a group. Ståle Solbakken's system accentuates their direct, transition-heavy approach, maximizing space for Haaland's devastating runs.
Norway hasn't been a regular World Cup participant, but 2026 feels different. Led by Erling Haaland and Martin Ødegaard, Norway finally has both star power and structure. They arrive with serious momentum, reportedly dominating qualification with a perfect record and high goal output. This isn't just a one-man team anymore. If they survive a tough group, they could become one of the most dangerous knockout sides.
The challenge is genuine. They will face some tough teams in the group stage, with Senegal and France coming up after an opening fixture against Iraq. Group I is arguably the most demanding in the tournament for a qualifier behind France.
But consider this: it will hope to have midfield heartbeat Martin Ødegaard purring alongside the steady Sander Berge, with midfield balance key to Ståle Solbakken's 4-4-2. This is not a one-trick pony built entirely around Haaland. This is a functional, tactically coherent squad playing its first World Cup of the 21st century with something to prove.
At 26.50 on Duelbits, Norway represent the best combination of outright odds and genuine probability of any team on this list. If they make the knockout rounds, Haaland's goal-scoring ceiling against tired defences in the Round of 32 makes them extremely dangerous.
The Haaland factor: The Premier League's all-time single-season scorer has never had the opportunity to perform on the World Cup stage. Every other elite player has had their World Cup moment, Messi, Ronaldo, Mbappé. Haaland arrives starving for his.
Verdict: The most analytically compelling dark horse bet in the tournament. Back Norway at 26.50 and include them to qualify from Group I at 1.20 as a more conservative position.
Group K: Portugal (Group Favourite), Colombia, DR Congo, Uzbekistan
To qualify from Group K: Colombia - Yes at 1.14, No at 5.50
Luis Díaz is thriving at Bayern Munich, while Luis Suárez has been prolific for Sporting CP in Portugal. Jhon Córdoba continues to deliver in Russia, Cucho Hernández is flourishing at Real Betis and Jhon Durán, despite frequent club moves, remains a mercurial, unpredictable threat. The firepower is genuinely frightening.
If James can stay fit and find his best form, Colombia are a real threat to anyone in the knockout rounds.
Colombia have quietly rebuilt, blending youth and experience into a side that now looks well balanced. Luis Díaz is the spearhead, ably supported by James Rodríguez's creativity and a new generation of energetic midfielders. The team's structure, under Néstor Lorenzo, combines resilience with a willingness to play on the front foot. A favourable group draw and strong support in North America, where Colombian fans travel in numbers, set the stage for early momentum, and the squad's familiarity with climates similar to those in the USA adds a subtle edge.
2014's unforgettable protagonist, James Rodríguez, is still lurking, and the veteran playmaker is complemented by an exuberant attack. Their Group K draw, alongside DR Congo and Uzbekistan, is one of the most navigable paths to the knockout rounds of any dark horse in the field.
Yet caution lingers. A six-match winless streak before sealing qualification against Bolivia exposed its inconsistency. Backing such a streaky side carries risk, but whatever its fate, Colombia promises entertainment.
The inconsistency is real. But Uruguay and Colombia would be more traditional South American dark horses, and Colombia's attacking output, Díaz at Bayern Munich is a different level of player from when he was at Porto, represents genuine quarter-final quality.
Verdict: The best pure outright value in the entire World Cup 2026 market. Colombia at 35.00 for a team with Bayern Munich's leading winger, Colombia's most complete midfield in a decade, and one of the more accessible knockout bracket pathways of any contender.
Group F: Netherlands (Group Favourite), Japan, Sweden, Tunisia
To qualify from Group F: Japan - Yes at 1.28, No at 3.50
Japan have quietly become one of the most exciting teams in world football, and the 2026 World Cup could be the tournament where they truly announce themselves on the global stage. Packed with players from Europe's top leagues, their high-pressing, high-intensity style of play caused Germany significant problems at the 2022 World Cup, and they will be determined to go even further this time.
Japan is no longer just a 'dark horse'. In recent years, they've become a proven threat. They beat Germany and Spain in the 2022 edition and have continued that momentum with strong performances and wins over top European sides in recent friendlies. With players like Kaoru Mitoma and Takefusa Kubo, and a tactically disciplined system, Japan combines speed, structure, and fearlessness.
There's a synergy to Japan's play that renders them similar to a cohesive club outfit, with efficient usage of possession complemented by a modern approach without it. Moriyasu has been in charge since 2018, and there's a sense that the culmination of his tenure could arrive at his second World Cup. The Blue Samurai is not defined by its individuals, but rather its collective makeup. Kaoru Mitoma is the game-changing cog of a well-oiled machine, and Ayase Ueda is one of Europe's leading goalscorers this season.
It's easy to envisage this Japan team joining the likes of '94 Bulgaria, '02 Türkiye and '22 Morocco as one of the most memorable World Cup dark horses.
Group F has the Netherlands as clear group favourites, but Sweden and Tunisia as the other opponents. Japan need to finish second in a group where they have already demonstrated the ability to beat better opposition than any of these teams.
Verdict: At 51.00 for a team that beat Germany and Spain four years ago and has only improved since, Japan are structurally underpriced. Their counter-pressing tactical system that causes elite teams genuine problems makes them the most dangerous 50-1 shot in any tournament betting market this year.
Group C: Brazil (Group Favourite), Morocco, Scotland, Haiti
To qualify from Group C: Morocco - Yes at 1.12, No at 6.00
Morocco captured the hearts of the football world at the 2022 World Cup, becoming the first African nation to reach the semi-finals with a brand of football that blended defensive organisation with devastating counter-attacks. They haven't slowed down.
Morocco uses a strong defensive system and fast ball movements to maintain their status as one of the most organised teams in international soccer.
Morocco arrive as one of the most credible World Cup dark horses after recent tournament success. Their defensive geometry, midfield compactness and emotional discipline deny superstars oxygen.
The controversy around the 2025 AFCON has actually added a motivational dimension: despite ending on the losing side in the AFCON final, they have been crowned champions after Senegal were disqualified. This surely adds to their momentum.
That could open the door for Morocco in Group C. The Atlas Lions reached the semifinals of the last World Cup, and they were recently crowned champions of Africa.
Their Group C path, Brazil as the dominant first-place team, Scotland and Haiti as the other opponents, gives Morocco one of the clearest routes to qualification in the tournament. They don't need to beat Brazil; they just need to finish second ahead of Scotland.
Morocco's journey in 2022 showed exactly what is possible with a well-organised defensive structure and dangerous set-piece and transitional attacks. Sweden and Bulgaria were semi-finalists the last time the World Cup was held in the USA in 1994, and Croatia have reached at least the semis three times since 1998. History shows that determined, cohesive units from outside the traditional elite can succeed in the North American environment.
Verdict: Morocco at 51.00 for a team that reached the semi-final four years ago, won AFCON, and has the defensive framework to defeat any team on a given day. This is not a speculative longshot, this is an undervalued semi-final contender.
Group D: USA (Group Co-Favourite), Turkiye, Paraguay, Australia
To qualify from Group D: USA - Yes at 1.12, No at 6.00
The United States might not look like traditional contenders, but 2026 changes everything. Playing at home across multiple venues gives them a massive boost, something analysts believe could push them into the knockout rounds and beyond. With a young, energetic squad led by Christian Pulisic and coached by Mauricio Pochettino, the U.S. has pace, depth and now, crowd support. If they build momentum early, they could ride it deep into the tournament.
The case for the USA as potential World Cup outsiders is simple: a wave of support, rising stars, and the absence of travel fatigue.
As co-hosts, the USMNT did not need to qualify for the 2026 World Cup, making it slightly harder to gauge its true level. Over the past six months, however, the team appear to have finally clicked under the Argentine. It reached the Gold Cup final before falling to Mexico and has since impressed in friendlies, most notably thrashing Uruguay 5-1 in November.
The home nation factor in football is well-documented. Host nations such as the United States, Mexico and Canada carry elevated expectation in their World Cup 2026 projections. Seven of the last eleven World Cup tournaments have seen the host nation reach at least the quarter-finals. The USA have the individual quality, Christian Pulisic, Gio Reyna, Tyler Adams, Ricardo Pepi, to make that happen in 2026.
Its inability to keep clean sheets, though, with a vibrant attack and midfield masking a shaky defense, could ultimately prove its undoing. This is the caveat. The USA's defensive vulnerability means they can be picked apart by technical teams, but Group D (Turkiye, Paraguay, Australia) doesn't contain any. A group stage free from major defensive tests could allow the USA to build momentum before the knockout rounds begin.
Verdict: At 66.00, the USA host-nation factor, home crowd advantage across multiple US venues, and the improving quality of their attacking talent represent exceptional each-way value. This is the most commercially interesting outright on the entire list for US-based fans.
Ecuador is an outstanding defensive team. Its qualifying campaign was notably impressive, conceding just five goals in 18 games. The team draws a lot of games, but no one has beaten it since the start of 2025. The Netherlands and Morocco, two potential outsiders this summer, were held to 1-1 draws in March.
Ecuador split Argentina and Brazil in CONMEBOL qualifying. A team that goes unbeaten since early 2025, concedes almost nothing, and regularly holds elite teams to draws is exactly the kind of dark horse that can grind their way through an expanded knockout format. Group E contains Germany plus Ivory Coast and Curacao, a navigable second-place run followed by a potential 32-team bracket where defensive organisation matters more than star quality.
| Team | Duelbits Outright | Group | Best Path |
|---|---|---|---|
| Norway | 26.50 | Group I (France) | Qualify 2nd, knockout run |
| Colombia | 35.00 | Group K (Portugal) | Best dark horse value |
| Japan | 51.00 | Group F (Netherlands) | Proven giant-killers |
| Morocco | 51.00 | Group C (Brazil) | 2022 semi-finalists |
| USA | 66.00 | Group D | Host nation factor |
| Ecuador | 78.00 | Group E (Germany) | Defensive fortress |
For maximum entertainment across the tournament, combine all five in an outright accumulator: Norway, Colombia, Japan, Morocco, USA all to make the semi-finals, priced individually, the combined parlay would return life-changing money on a small stake.
For more conservative play: Norway to qualify from Group I (1.20) combined with Japan to qualify from Group F (1.28) combined with Morocco to qualify from Group C (1.12) creates a three-team qualifier accumulator at approximately 1.73 combined, paying on near-certainties with good return.

More matches mean form teams can ride runs deeper into the tournament.
